Remarks
Applies a Pitch change to the given portion of sound under editing. A pitch change will affect sound pitch or key, without affecting the sound tempo or playback rate so the sound duration won't be altered.
During the execution of the editing session the CallbackEditPerc delegate is invoked in order to notify about the percentage of advancement.
For further details about callback delegates see the How to synchronize the container application with the API tutorial.
For further details about methods related to the use of special effects refer to the EffectsMan class.
